COOKING-STOVE.

Specification forming part of Letters Patent No. 92,665, dated July 13, 1869.

To all whom "it may concern:

Be it known that I, ELIHU SMITH, of the city and county of Albany, and State of New York, have invented a new and useful Improvement in Cooking-Stoves; and 1 do hereby declare that the following is a full, accurate, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification.

Figure 1 represents the body of myimproved cooking-stove, with openings showing the location of the fire-box, oven, and also the places for boilers, kettles, &c., on the top of the stove; also, openings for the exit-flues. It shows the extension-plate also. Fig. 2 represents the top part of the stove, showing an elevated boiler, in combination with a superficial oven. It also shows a grooved way or track, on which is placed a sliding plate to receive and transport a movable boiler and other vessels for cook- Fig. 3 represents said top part of the stove with movable boiler in position, with lateral extended flues sustaining crosshead with cross-flues, capable of being converted into a heating apparatus or oven, as hereinafter described, and as represented in Fig. 2. Fig. 4 represents the flues E E E and the dampers belonging to each, respectively, as they would appear if the top plate of the stove were removed. Fig. 5 represents the grooved way and the sliding plate as they would appear in operation, shown in Figs. 1 and 2. Fig. 6 represents the plate used for extending the top plate of the stove, as shown in Figs. 1 and 3. Fig. 7 represents a cover of the kind to be used in covering or closing the lines E when they are not desired to be used as flues.

My said improvements consist First, in the arrangement of the fines and dampers, as represented in Fig. 4, where E represents the tines, and D the damper for closing the middle flue, and D D thedanipers for closing the side flues.

Second, in an arrangement by which I use a movable boiler by means of a sliding plate and grooved way in the top of the stove or top plate. The movable plate A, for receiving and transporting the boiler, is in position on its track in Figs. 1 and 2.

. Third, in the arrangement of a separateezetension-plate, with or without open-work bottom, which I attach to the top plate in the rear of the flues, as represented in Figs. 1 and 3.

Fourth, in the arrangement of a boiler, placed upon the top of extension-flues, the crossflues uniting with the exit-flue at the center of the boiler and forming a support and even bottom to the boiler, as represented in Fig. 2. By this arrangement the cross-flue, serving as a support and bottom of the boiler G, together with the exit-flue 0, acts as means of heating the water in the boiler.

Fifth, in the arrangement of a superficial oven or warming-closet by inclosing the space between the extension-flues F F, supporting the boiler G, and between the top plate of the stove and the arched cross-flue K, by any suitable means, as represented in Fig. 2. The drawing referred to represents a tin back and side cover, constructed to fit upon the top plate of the stove covering closely the sides, back, and top in the rear of the extension-tlues, and the bottom of the elevated boiler. This oven extends back over the extension-plate, and is completely inclosed by means of a tin or other cover in front, fitted to the top plate of the stove, to the upright flues, and to the bottom or front side of the elevated boiler.

Sixth, in the arrangement of two cross-flues, connecting. the extension-flues F F, in combination with the said extension-plate and the movable boiler, as shown in Fig. 3.

The construction and operation of my said flues and dampers are as follows:

When I wish to use the two side flues as such flues, the cover h, Fig. 7, is placed over the center flue, E, as shown in Fig. 1. In such case, the dampers being opened, the products of combustion pass down the center flue under the oven and return up through side and cross flues to the exit-flue. In case the side flues are to be dispensed with, covers like h are placed over each of the side-flue openings in the top plate of the stove, closing them, and the exit-pipe is connected with the center flue, E, as in theordinary stove.

The dampers are useful only in determining the manner in which the products of combustion shall pass under the ovenwhen it is desirable to heat the same, and must be used with reference to the exit-flues to be used. The movable boiler is constructed and 0perates in the manner following It is desirable to have means of heating water very speedily, and when no longer needed to have it removed out of the way, where it maybe kept at any desirable temperature beneath the boiling-point. To accomplish this I have arranged a grooved way in the top plate of the stove, to which I have adjusted a sliding plate with projections at each end on the under side of the same, to move in and be guided by these grooves, as shown in Fig. 5. Upon this plate I place my boiler or. other vessel. When it is desirable to heat water for immediate use the plate can be drawn forward and the boiler placed over any of the openings over the fire or other part of the stove. When the top .of the stove is required for other use the plate with the boiler can be pushed back under the cross-head and onto the extension-plate out of the way.

The object of my extension-plate is to extend the top plate of the stove, when the same is needt'ul for any of the purposes herein described; and it is constructed as represented in Fig. 6, and attached to the top plate of the stove by means of openings cast therein to receive the projections on such extension-plate, as represented in Fig. 6.

The boiler, which I place upon the top of my extension-fines F F, as shown in Fig. 2, is 0011- structed in the usual manner of making boilers for the top of stoves, with this difference: I use the bottom of said boiler for the top of my arched cross-flue K, connecting with the exit-pipe O at the center of the boiler, so that the eross-flue K and the exit-flue O serve as means for heating the water within the boiler.

My elevated or superficial oven is constructed as follows: I use the space included between the side flues, the top of the stove, and the bottom of the cross-flue K, and iuclose the same by any suitable means, extending the space over the extension-plate in the rear and as far forward as may be desirable. This oven is heated by means of radiation through the top plate, the side fines, and thecross-flue, as they are shown in Fig. 2. The oven may be provided with shelves, as seen at H in said figure.

The extension-fines and elevated boiler may be attached to the main body of the stove by means of hooks, as represented in Figs. 2 and 3. They may be thus connected by any suitable means.

Having thus fully described my said invention, what I claim as my invention, and desire to secure by Letters Patent, is-- 1. The arrangement of a movable boiler upon the top of the stove, constructed and used in the manner and for the purposes substantially as described.

2. The elevated boiler upon the extended and cross flues, having the cross-flue K as a part and support of the same, constructed substantially in the manner and for the purpose above set forth.

3. The superficial oven constructed substantially as above described, in combination with the upright and cross flues above represented and described.

4. The extension top plate 13, in combination with'my movable boiler and railway, substantially as above described.
